Origin

Compound word

构词法gòucífǎ

偏正piānzhèngModifier + head

The first part narrows down the second: it says what kind of thing the head is.

目镜 is a 镜, lens, placed at the 目, eye.

Characters in this word

A drawing of the thing itself, worn down over three thousand years into a few strokes.

目 began as a drawing of a human eye, turned sideways.

Most characters — around four in five — are built this way: one part hints at the meaning, the other at the pronunciation.

This origin belongs to the traditional form 鏡; 镜 is its simplified writing.

金竟鏡

Meaning part形符xíngfú

金金jīnmetal

Sound part声符shēngfú

竟

竟jìng鏡jìng

Same sound today

The traditional form 鏡 puts 金, metal, next to 竟 to give the sound. The simplified 镜 is a later shorthand.
